Caudal regression syndrome (sirenomelia) and its pathogenesis correlation: a case report

Synthesis of Nickel Ferrite NiFe2O4 Nanoparticles/PVA composite and studying Its electric properties

“…Where after calcination at 550°C as shown in Fig. 1c the remaining two weak peaks lies in region (1560 and 2364) cm -1 are due to the stretching vibrations between octahedral metal ions and oxygen ions Hence the two strongest peaks confirmed the spinel structure of NiFe 2 O 4 in region (628 and 549)cm -1 according to Waldron [12,13].the high frequency band υ 1 around (628)cm -1 is attributed to that of tetrahedral complexes. The band υ 2 around (549)cm -1 corresponding to octahedral complexes.…”

Understanding Caudal Dysplasia Sequence: Three Case Reports

“…There is underlying developmental disruption of structures derived from the caudal mesodermal axis of the embryo during the primitive streak stage. 5 Two important theories that have been proposed to explain the cause are the vascular steal hypothesis and the defective blastogenesis hypothesis. 6 Poor glycemic control in diabetic mothers before the eighth week of development exposes the embryo to hyperglycemic insult.…”
